[undertow-dev] java.lang.NoClassDefFoundError: freemarker/cache/TemplateLoader

Hi, I am just creating a Hello world example of undertow.js like so $undertow .onGet("/hello-freemarker", {template: '/resources/hello.ftl','template_type': 'freemarker', headers: {"content-type": "text/plain"}}, [function ($exchange) { return {data: 'Hello World!'}; }]); When deploying the project I am getting the following exception ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 2) MSC000001: Failed to start service jboss.undertow.deployment.default-server.default-host./undertowjs-example: org.jboss.msc.service.StartException in service jboss.undertow.deployment.default-server.default-host./undertowjs-example: java.util.ServiceConfigurationError: io.undertow.js.templates.TemplateProvider: Provider io.undertow.js.templates.freemarker.FreemarkerTemplateProvider could not be instantiated at org.wildfly.extension.undertow.deployment.UndertowDeploymentService$1.run(UndertowDeploymentService.java:85) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) I have also added the freemarker jar file in the modules folder but it still doesn't help. Please let me know what I might be doing wrong or is come extra conf required. -- Best Regards *Shiva Saxena* *Mobile : +91-9889787094 * *Blog <http://metalop.com/> | Linkedin <http://in.linkedin.com/in/shivasaxena/> | StackOverflow <http://stackoverflow.com/users/2490343/shiva>*
